DEVICE FOR HEATING AND LIGHTING APARTIVIENTS.

SPECIFICATION forming part of Letters Patent No. 554,591, dated February1 1, 1896. Application tiled January ll, 1895. Serial No. 534,552. (Nomodel.)

To all whom it may concern:

Be it known that I, PETER FRASER, of Whitman, in the county of Plymouth,State of Massachusetts, have invented certain new and usefulImprovements in Devices for Heating and Lighting Apartments; and I dohereby declare the following' to be a full, clear, and exact descriptionof the same, reference being had to the accompanying drawing, forming apart of this specification, and'to the letters of reference markedthereon.

The invention has for its object to provide, primarily, a heating devicewhich shall be capable of utilizing in-the most efficient manner all ofthe heat derived from the flame of a burner, be it coal-oil or gas, toheat a body of air and distribute the air so heated through theapartment, a further object being to provide a convenient arrangement ofdevices whereby the elevation of the heater and burner may be changed atpleasure.

The invention consists in certain novel details of construction andcombinations and arrangements of parts to be hereinafter described, andpointed out particularly in the appended claims.

The accompanying drawing represents in section a heater, together with aburner attachment embodying my present invention,

certain of the parts and the supporting mechanism being shown inelevation.

The lett-er A indicates a burner, such as a coal-oil lamp which gives agood strong iiame, preferably of the Argand type, or a gas-burner ofsimilar character. This burner is supported on the lower end of a slidecarriage or frame B, which at the upper end carries the heatingmechanism to be presently described.

The carriage or frame B is mounted to slide on a vertically-arrangedbracket or way C, which may be secured to the wall or other support attop and bottom, as shown, and to facilitate the adjustment of the frameor carriage on its bracket or way a counterweight D, sliding in a boxingD and connected to the carriage by a iiexible connector d passing over apulley d', is provided. The counterweight balances approximately theweight of the heating device and burner, and in order to hold thecarriage in its adjusted position should a slight excess of weight lieon one side or the other, occasioned, for instance, by

the consumption of oil, I provide a spring E, having its ends passedbeneath movable yokes E' extending around the bracket or way andattached to the carriage or frame B by bolts or pins e at top andbottom. The center of this spring bears against the carriage and forcesthe latter into frictional contact with the bracket or way, and thisfriction is sufticient to prevent any accidental movement of thedevices, although it permits of their adjustment when desired.

The heating mechanism proper consists essentially, first, of arelatively long narrow dome or chamber suspended directly over theburner-chimney, preferably with its lower edge below the top of the saidchimney and in position to receive all of the productsheated air,gaseousproducts, Ircpassing out of the chimney. At the top this dome orbell, which I shall hereinafter term the radiator F, is preferablyprovided with small perforations f to allow the products to escape andinsure a circulation and change of air within the radiator. Thisradiator is preferably suspended on a central pivot at the top, and itwill be particularly observed that this radiator is of relatively smalldiameter and great length. Thus the highly-heated products entering thesame pass rapidly up and heat the whole of the radiator-walls to a veryhigh degree, thereby providing a radiating-surface of comparativelylarge area, and with a View to further increasing the efficiency of theradiator it is preferably constructed of copper, which materialtransmits the heat from the interior column of heated air or products tothe exterior of the radiator with very great facility.

Outside of the radiator and entirely surrounding the same is a hot-airconductor G, having a flaring or bell mouth G' at the lower end andterminating at the top in a hood G2, beneath which hood are formed aseries of exit-openings g for the escape of hot air passing up throughthe conductor. The bellmouth of the conductor catches all of the hot airpassing up around the burner proper and all of the products escapingfrom the radiator either at the bottom or top, and these, united withthe large body of air flowing rapidly up through the conductor, andbeing heated to a high degree by the radiator, furnish a very largevolume of hot air to the apartment. This ICO heated air may be allowedto iiow out naturally if desired, but I prefer to dissipate it laterallyby means of a fan-wheel I-I arranged vertically, or on a horizontalaxis, opposite a lateral opening h. This fan is driven through a pair ofbeveled gears I from a horizontallyarranged motor-wheel K, located inthe conductor immediately above the radiator, and in position to bedriven bythe ascending col umn of heated air.

In the preferred construction the fan mechanism is preferably mounted inan independent section G of the conductor G. Thus it may be removed inits entirety and the hood G2 fitted down directly on the conductor.

As before stated, the radiator is preferably suspended from a singlepivot at the top, which in turn may be supported from a crossbar, suchas m, and at the bottom the radiator is held against excessive vibrationby means of a series of springs, such as M,which springs also serve tocenter the radiator over the burner under all conditions of use, and atthe same time permit of a certain degree of flexibility or yielding,which is desirable in order to permit of the device being handled and ofthe radiator maintaining its true vertical position, so as to secure thegreatest efiiciency.

The burner being located beneath the level of the conductor and radiatoris left exposed and may be utilized as an ordinary gas or lamp burnerfor lighting apartments, and in addition the flaring mouth G and bottomof the radiator may be made in the form of reflectors, which willintensify the light thrown down from the burner to a certain degree.Thus with the combination shown not only is the heating effect of theburner vastly increased, but the light is also properly directed so asto be capable of utilization to the greatest advantage.

Having thus described my invention, what I claim as new is- 1. In adevice such as described, the combination with the burner, its chimney,and the substantially cylindrical hot-air conductor having the iiaringmouth at the bottom and a discharge-opening at the to p, of the long`approximately cylindrical radiator suspended concentrically within theconductor with its lower end at the top of the chimney, means forpositioning and independent supports for the burner and conductor;substantially as described.

2. In a device of the character described, the combination with theburner, its chimney and the relatively long narrowr radiator suspendedover the chimney in position to receive the heated products passingtherefrom, of the flaring-mouth conductor surrounding the radiator withits walls parallel therewith and springs for preventing the excessiveswinging of the radiator within the conductor 5 substantially asdescribed.

3. In a device of the character described, the combination with theburner, the relatively long narrow radiator suspended above the same inposition to receive the heated products from the burner, theilaringnnouth conductor surrounding the radiator, thehorizontally-arranged fan in the upper end of said conductor and thevertically-arranged fan driven by the horizontal fan i'or dissipatingthe heated air passing through the conductor; substantially asdescribed.

4. In a device of the character described, the combination with thevertical bracket or way of the carriage sliding thereon, thefriction-brake for holding said carriage in adjusted position, thevertically-arranged radiator and conductor mounted on the carriage andthe counterweight for balancing the weight of said parts; substantiallyas dcscribed.

5. In a device of the character described, the combination with thevertically-arranged bracket or way, the carriage sliding thereon, thefriction-brake for holding the carriage in adjusted position and thecounterweight, of the burner mounted on the lower end of the carriageand the radiator and haring-mouth conductor mounted on the upper end ofthe carriage whereby the level of the heater and burner may besimultaneously altered; substantially as described.
